Do you have this recent TurboTax software-update Microsoft error?

It says it's a "Microsoft Error" of some sort:

*Microsoft installer error: 1326 Failed to install update.*
.. Anyone else having recent issues updating TurboTax Win10 software?

Every year, the one program I purchase for Windows, is TurboTax:

I installed this TurboTax on Windows 10 months ago, as I was getting ready
for April 15th, but then they extended the deadline, so now I'm getting
back to finishing up my federal taxes using Turbotax on Win10 Pro.

It insists on updating whenever I try to run a review, for example:

Or even when I open an existing tax file, for example:

Yet, some things do work just fine, as far as I can tell:

There's a notification in my Turbotax inbox, but it's just covid stuff:

For days now, every time I try to update, I get this message:
.. TurboTax 2019 - Update
... Failed Updates:
.... Program Updates (Critical)
..... Failed to install update. Microsoft installer error: 1326,
Error getting file security:
C:\ProgramData\Intuit\ GetLastError: 5 "Check for solution"
(Released 6/6/2020) Program Updates "More details"

When I click on "Check for solution", it comes up to:
.. https://support.turbotax.intuit.com/viewResult.jsp?act=1&prid=4&docid=SLN46781&id=3355 4432
Which says:
"We're sorry, the page you requested could not be found"

When I click on "More details", it comes up to:
.. http://turbotax.intuit.com/support/in-product/434-release-notes-2012-ind/
Which then changes to:
.. https://ttlc.intuit.com/community/using-turbotax/help/turbotax-release-notes-for-windows-personal-tax-software/00/26799
Which is utterly worthless.

I called TurboTax at 800-358-6057 who told me to press
.. {shift+enter}
Which popped up a code for them to view my screen as I tried it again.
.. But in the end, they were as befuddled as I was as to the cause.

They said it's some kind of "Microsoft security" problem...
.. Based on the error message itself...

So they told me to call Microsoft.
.. Anyone else having a problem updating Turbotax 2019 recently?
